Dear User,

This is something you really should take a look at. It can be the start of a new life strategy. NSDR, which stands for “Non-Sleep Deep Rest” protocols provide help to optimise your mind for both relaxation and learning. And, as it says in the name, it doesn’t involve sleeping! The term was coined by the American neuroscientist Dr. Andrew Huberman, mainly to make it appealing to those who may be turned off by more esoteric or spiritual concepts like meditation or yoga.

NSDR is a powerful tool that allows you to have control over your nervous system and your overall state of mind. It has the amazing ability to reset your energy levels and awareness, without the need for focus as with meditation. And although the results are very similar, Huberman insists energetically that it is not meditation and that a clear distinction should be made.

“Whereas meditation involves a lot of activity in your prefrontal cortex, NSDR puts you in a very calm and relaxing state where you don’t have to do any work; you just listen.”

This makes it a perfect addition to the SonicTonic toolbox!

Research shows that being in a deep state of relaxation but also high focus drastically improves neuroplasticity, which is basically the re-wiring of your brain. This means you can learn much faster, and retain new information easier

NSDR can be the start of a new life strategy with less worry and anxiety. It helps stop the discomfort caused by anxious or intruding thoughts. It reduces rumination and mind wandering, and your mind can feel less ‘crowded.’

There are protocols that can help you to focus and improve your performance. You can be productive and positive, despite the stress and uncertainty you may feel.


NSDR protocols trigger a deep state of profound relaxation in which the body and mind are both restored. 

It involves entering Altered States of Consciousness and being in a dreamlike state  where our minds are at rest but we’re not  sleeping.

NSDR not meditation; it’s a technique that helps you to relax and make it easier to focus and replenish your nervous system.
